1979 - Two RAFHawker Siddeley Harrier jump-jets from RAF Wittering collide over the UK. Both pilots ejected safely. One of the jets broke up in midair and fell harmlessly into a field but the other dropped onto the centre of Wisbech in Cambridgeshire, destroying two houses and a bungalow. Several people were injured in the accident - including a mother and her baby - and three people were killed.
